HYDROCARBON TIRE-HEATER.

SPECIFICATION forming part of Letters Patent No. 218,567, dated January13,1903. Application filed June 19,1902. Serial No. 112,888. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM W. DAVIS, a citizen of the United- States,residing at Baldwin, in the county of Lake and State of Michigan, haveinvented a new and useful Hydrocarbon Tire-Heater, of which thefollowing is a specification. I f

This invention relates to devices employed for heating vehicle-tires;and it has for its object the production of a device wherein liquid fuelis used as the heating medium.

The invention consists in a series of independently-controlled segmentalburners concentrically disposed and supported upon a frame, which alsoserves as a support for the tire while being heated.

The invention further consists in certain novel features ofconstruction, as hereinafter shown and described and finally pointed outin the claims.

In the accompanying drawings, Figure 1 represents a plan view of thedevice complete. Fig. Zrepresents a sectional side elevation thereof.Fig. 3 represents an enlarged sectional detail of one of theburner-segments.

, The same reference-numerals indicate corresponding parts in.all thefigures.

The device as illustrated comprises a central receiver 10, into whichthe liquid fuel is fed through the pipe 11, having a controllingvalve 12and leading from a suitable reservoir, here shown as a tank 13, providedwith a nipple-valve 14, through which compressed air may be supplied tothe tank to produce a force feed to the burners when necessary.

The receiver 10 is preferably tubular and disposed in a verticalposition, and, as shown,

e is composed of a section of tubing closed at the lower end and havinga screw-cap30 forming the closure at the upper end, with the feed-pipe11 leading downwardly through the center of the cap. Radiating from thereceiver at equidistant points are pipes 15, of which any desired numbermay be employed, four being here shown. Branch pipes 16 are mounted forlongitudinal adjustment on the pipes 15, preferably by means ofexpansionjoints, as 17, of the ordinary construction, which permit thelongitudinal extension and adjustment of the pipes 16 with relation tothe Rising from each of the pipes 16 pipes 15.

are spaced upwardly-extending branches, as 18 28, and each of saidbranches is provided with a segmental horizontally-disposed burner ever,be placed on the inner side of the burners when desired, as shown at 27in Fig. 3. Each of the branches 18 28 is supplied with acontrolling-valve, as 31 32, respectively, so that each burner may beindependently controlled to, regulate the amount of heat applied tovarious parts of the tire. The burners are so disposed that whenadjusted to their innermost positions their adjacent ends will be nearlyor quite in contact, thereby forming two complete spaced circles orcircular burnerswith the flamesburningoutwardlythrough the apertures,the degree of heat to be applied to various parts being under thecontrol of the operator.

The radii of the inner set of segmental burners correspond to thesmallest size of tire which it is designed to heat, and the radii of theouter sets correspond to the tires of the rear wheels of the samevehicle to which the smaller tires belong, so that both sets of tiresmay be heated at the same time, if desired. The device is capable ofbeing adj usted to fit any size of tire by means of the1ongitudinally-adjustable branch pipes 16, the piping, valves, andburners being of any required size to adapt them to all sizes of tires.

Disposed beneath the radiating pipes 15 is a supporting annular frame21, having legs 22, connected intermediately of their length thereto andextended downward to the supporting-surface on which the device rests,the upper ends thereof being turned outward, forming horizontal members22 for engagement with the under surfaces of the burners 19, and theouter ends of the members 22 are bent downwardly, forming legs forengaging the supporting-surface. By this means the whole device isfirmly supported and braced, the band member 21 supporting the radiatingpipes 15, the leg members 22 supporting the band member 21, and thehorizontal members 22 supporting the burners and the tire to be heated,at the same time leaving the burners free to be adjusted longitudinallywithout disturbing the tire being treated. The horizontal members 22also serve to support the outer ends of the extension-pipes 16 throughthe connecting vertical brancheslS, having the burners 19 connectedthereto and resting on said horizontal members, so that theexpansion-joints 17 are re lieved from any lateral strain which wouldotherwise have a tendency to twist the expansion-joints and cause themto leak.

The whole device is compact and interdependent and readily adjustable tofit varioussized tires, each set of burners being independent from allthe others and each burner individually independent by reason of itsindependent controlling-valve.

By so constructing the device any one burner or series of burners may beused or shut off as desired, so that any particular part of a tire ornest of tires may be heated to a higher degree than the other parts.

The central reservoir is heated by a torch, lamp, or other suitablemeans when the apparatus is first started to cause the hydrocarbonfedthereto to vaporize therein, so that the fuel so vaporized willescape from the burners in condition to be ignited, and after theburners are heated sufficiently to vaporize the fuel as it passesthrough them the device becomes self-acting.

I claim as my invention- 1'. In a device of the class described, areceiver for theliquid fuel, pipes radiating from said receiver, branchpipes mountedfor lon-. gitudinal adjustment on said radiating pipes,burners carried by said branches, controllingvalves in said branches,and an annular supporting-frame engaging said radiating pipes.

2. In a device of the class described, a receiver for the liquid fuel,pipes radiating from said receiver, branch pipes mounted forlongitudinal adjustment on said radiating pipes, burners carried by saidbranch pipes, controlling-valves in said branch pipes, an annularsupporting-frame having a rest for said radiating pipes, andsupporting-legs extending from said annular frame beneath said segmentalburners and affording supports therefor and for the article beingheated.

3. In a device of the class described, a receiver, pipes radiating fromsaid receiver, branch pipes mounted for longitudinal adjustment on saidradiating pipes, segmental burners carried by said branch pipes, a cen-'tral frame supporting said receiver and radiating pipes,extension-frames engaging said central frame and supporting-said burnersand the branch pipes connected thereto and also supporting the articlebeing heated.

4. In a device of the class described, a receiver, pipes radiatingtherefrom, branch pipes mounted forlongitudinal adj ustment on saidradiating pipes, spaced pipes extending upwardly from said branch pipes,segmental burners carried by said upwardly-extending pipes, each ofsaidupwardly-extending pipes having a controlling-valve for regulating thesupply of fuel to the burner carried thereby.

5. In a device of the class described, a receiver, a feed-pipe leadingthereinto, a controlling-valve in said feed-pipe, pipes radiating fromsaid receiver, branch pipes mounted for longitudinal adjustment on saidradiating pipes, segmental burners carried by said branch pipes anddisposed concentrically to said receiver, independent controlling-valvesin said branches, an annular frame supporting said radiating pipes,verticallegs engaging said annular frame and having radiallyextendingmembers forsupporting said burners and the article being heated thereby.

6. In a device of the class described, a receiver, pipes radiatingtherefrom and having burners connected therewith, and an annular framesupporting said radiating pipes, supporting-legs connected. to saidannular frame intermediately of their length and havingradially-extending members at their upper ends forming a support forsaid burners and for the article to be heated, and members extendingdownwardly from the outer ends of said radial members and adapted toengage a supporting-surface.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in the presence of two witnesses.

WILLIAM W. DAVIS.
